Kentucky Sen. Rand Paul, best known for his libertarian ideals, exited the GOP race for the presidential nomination this week amid disappointing results in the Iowa caucus.

Here is a snapshot of Paul’s climate change positioning:

Most recently, Paul suggested policymakers need to “balance control of pollution with the economy. We can’t get too crazy on one side or the other.”

At the GOP debate in November, Paul responded to a climate question by stating: “The first thing I would do as president is repeal the regulations that are hampering our energy that the president has put in place,” Paul responded. “While I do think that man may have a role in the climate, I think nature also has a role.”

Paul objected to the climate change deal struck in Paris and introduced a Sense of the Senate resolution requiring the deal to be approved by the Senate. “My resolution [reasserts] the Senate’s constitutional role in treaty review and [protects] the balance of power in our government.”
